Question

我正在关注如何创建API的napa api framework tutorial。但是在运行rake db:reset时会引发以下错误

WARN: Unresolved specs during Gem::Specification.reset:
  minitest (~> 4.2)

Please report a bug if this causes problems.

Answer 1

一年后，我遇到了类似的问题。我已经解决了。在尝试通过Mac OS El Capitan上的Napa快速启动时，我注意到它正在拉纳帕0.51这是不兼容的。我做的第一件事是改为napa 0.5.0。

接下来的事情是将活动记录4.2.0从4.0.0更改为摆脱最小的宝石问题。

我希望这有助于第一次访问napa并且无法让quicstart工作。

另外，我尝试使用MySQl快速入门，而不是本教程使用的Postgres。
